Quick VHO lighting question

[tifosi]

I have a 55 thats currently running 2 110 VHO 50/50's.
Its time to get new lights, should I stick with the 2 50/50's or should I mix one of one kind and one of another. BTW they are URI's. Thanks.

If you're happy with the color keep it the way it is. If you want more blue, swap the front bulb with a SuperActinic. If you want less blue swap the back bulb with an AquaSun.
IMO you should stagger the bulb swap. Swap one bulb every 6 months if you're running an IceCap ballast. Swap one bulb every 3 months if you're not.
This tends to balance out the light intensity better and is healthier for your corals.

Thanks for the advise....I may try one of the bulbs to be a Aquasun.
